简要总结
The aim of this comparative and reliability study is to highlight a deficit in the use of vibrotactile sensory feedback (haptic effect) in the planning and execution of fine manual dexterity movements after stroke. The investigators will include 3 groups of subjects, 1 group of young healthy subjects, 1 of older subjects matched in age and sex to the group of chronic stroke patients. Participants will take part in clinical tests of fine motor skills and sensitivity and will use a device to assess the key components of manual dexterity, to which vibrotactile sensors will be added. If they so wish, participants will be able to take part in a transcranial magnetic stimulation (TMS) study to assess the facilitation of cortical excitability due to the haptic effect.
详细描述
Firstly, the investigators would like to carry out a study into the validity of measuring haptic deficits using vibro-tactile sensors positioned on the hands of chronic stroke patients and young and elderly healthy subjects. They believe that identifying the haptic deficit using a simple and rapid method, in combination with motor training, could make it possible to improve the prediction of recovery and personalise the rehabilitation of manual dexterity deficits after stroke. They will also compare the effect of tactile feedback with that of auditory feedback in order to study the specificity of the effect of this feedback on manual dexterity. In the second part, to better understand this and to study the cortical mechanisms involved in sensory-motor integration, the investigators propose to measure the haptic effect on cortical excitability in stroke patients and healthy subjects using Transcranial Magnetic Stimulation (TMS).

Young Healthy Controls
The 3 groups, made up of participants with different pathologies and ages, will receive the same intervention (clinical motor and sensory tests and optional TMS). We are studying the difference in results between these groups.
